Sondrestrom Lidar Operation Log

Operator(s) : Christian Have Pedersen
Purpose : Data acq. on 532nm channel. Trouble shooting trigger problem with SR430.
Date(s) : 070906 - 070906
File(s) : L20070902_002 - L20070906_002
Comments : Trigger problem from last exp. did not show up in this experiment.
However, troubleshooting before this exp. did not show any obvious problems with
SR430 trigger, so the problem might have been a faulty cable, which inadvertely
was replaced?
Otherwise uneventful session.
